To all whom t may concern.'

Be it known that I, HARRY C. BROWN, a citizen of the United States, anda resident of lfiestwood, in the county of Bergen and State of NewJersey, have invented certain new and useful Improvements in Drilllliechanism, of which the following is a specification, taken inconnection with the accompanying drawings, which forma part of the same.

My invention relates to drill. mechanism and more particularly to meansfor feeding the drill point to the work. I have shown my invention inconnection with a combination tool illustrated, described and claimed inmy co-pending application Serial No. 799,945, filed September 20, 1913,of which this application is a division.

In the accompanying drawings showing illustrative embodiments of myinvention and in which the same reference numerals refer to similarparts in the several figures,-

Fig. 8 is a perspective view of the operating screw and a fragmentarysectional view of the movable jaw;

Fig. 9 is a plan view of the movable jaw;

Fig. 10 is a plan view of the base ring;

Fig. 11 is a detail view of a lathe plate which may be used with myimproved drill;

Fig. 12 is a detail showing one of the many tools which may be used withmy drill;

Fig. 13 is a detail view showing a different arrangement of mounting oneof the many tools which may be used with my device;

Fig. 14 is a detail view showing the manner of scoring to form, forexample, a key seat.

In the illustrative embodiments of my invention shown in the drawings, 1is an anvil having a hollow body member 2 and provided with the usualhorn 3, and hardy 4, and with a fixed jaw 21. 4The interior 5 of thehollow body member 2 may be of any suitable configuration to coperatewith the hollow supporting member G so that the latter will not rotatewithin the former. Preferably I provide the opening 5 in the hollow bodymember of the anvil 1 substantially rectangular in cross section tosnugly fit the hollow rectangular supporting member 6. I also providethe hollow body member with additional openings or pockets 7, 7 tocooperate with the locking head 8. This head is so formed as to snuglyfit the non-circular opening 5, in one of its positions, so that thelocking head 8 can be readily moved in and out to engage with thedifferent pockets or openings 7, 7 upon the operation of a locking bolt9. 85

This bolt 9 is preferably formed with a square or other non-circularhead 10 adapted to ybe received within the coperating recess 11 in thelocking head 8, its shank passing through the flanged thimbles 12 and 13and coperating with a nut 14.- which serves to prevent the locking bolt9 from becoming disconnected from the thimbles 12 and 13. The thimble 12has a flange 15 to engage the end of the rectangular hollow supportingmember 6, while the thimble 13 has a flange 16 to coperate with theinner flange 100 of the standard 17. On the end of the locking bolt 9 Ipreferably mount an operating handle 18 which I preferably, though notnecessarily, provide with a weighted end 19 so that it will normallyhang down and hold the locking bolt 9 in the position shown in Fig. 1,which will cause the locking head 8 through the work it will slipharmlessly within the aperture 22.

In those cases where it is desirable to use a very long drill point 55,the screw 31 may be rotated until the drill head 10 becomes adjacent to,or within, some of the female screw threads 33 of the screw 29. Such along drill point can be inserted through the opening in the fixed jaw 21and the opening 30 in the movable jaw until reaches the seat L1 in thedrill head 4:0.

While ordinarily the feed for the drill point is entirely done by thefeed screw 31, there are instances in which a preliminary feed may begiven by first screwing up 'the screw 29 and then subsequently screwingthe feed screw 31 so that both these screws 29 and 81 may serve as feedscrews for the drill point of the drill press as well as one of them,29, serving to operate the movable jaw 24e of the vice. But in allinstances, the work 53 is securely held in the vise without anyinterference from the operation of the drill.

In case the drill is not often used, it may be temporarily removed bysimply unscrewing the feed screw 31 from the screw 29, being againreplaced whenever desired, the combination tool meanwhile occupying lessspace.

The movable iaw is moved rcarwardl y upon the ref angdlar member 6 bythe end 56 of the screw 29 fitting within the open pocnet 26 of themovable jaw 24.- so as to )ermit the groove 28 to cooperate with theVlange 27 on the movable jaw, which will cause the movable jaw to moverearwardly with the screw in an obvious manner. The screws 29 and 81 areoperated by their respective handles 57 and 58.

r he standard 17 may be formed integral with the supporting member 6 butpreferably it is formed separate and snugly lits the supporting memberbeing prevented from becoming disconnected by the flange 16 of thethimble 13 cooperating with the flange 100 of the standard 17. Arrangingthe parts in this manner permits ready and cheap ree ne als in case ofbreakage from any cause.

In some instances I may form the operating screw to operate the movablejaw 59 of the vise with only male screw threads 60, Fig. 7, and providethe feed screw 61 for the drill with male screw threads 62 to engagewith female screw threads 63 in the movable jaw 59, though thearrangement previously described is the preferred construction.

My improved tool described is adapted to A erform all the functions ofan anvil, vise and drill and in addition that of a lathe, thread tap,scoring tool and other numerous uses, these being mentioned simply byway of example.

have shown in Fig. 11 a lathe plate 64 provided with a square boss 65 tobe received in the square drill socket @l1 of the drill head l0. lVhenthis lathe plate is mounted, for example, on the drill head 40, Fig. 13,and the work 66 is secured to the lathe plate 64 by the clamps 67, thedrill point 68 may be placed in the flared norcircular portions 23 ofthe opening 22, the work then being presented to the stationary drillpoint rIhe tool then performs the function of a lathe.

I may also tap holes with my improved tool. In Fig. 12 I have shown anintermediate socket 69 to be received within the flaring opening -l1 ofthe drill head lo, the intermediate member being provided with anon-circular opening 7 O for the reception of the shank 71 of the tap72. By the construction shown when the tap 72 begins to cut its screwthread, continued rotation of the drill holder d() and intermediatesocket 69, will cause the tap 72 to rotate and it will cut the threadsof the desired pitch regardless of the adjustment of the feed screw 81for the tap has a free independent axial movement in the socket whichpermits of its properly cutting its own screw thread by feeding itselfregardless of the adjustment of the feed screw 31.

In addition to performing the function of a lathe, my tool also performsthe function of scoring or otherwise operating upon wood 0r metal toform, for example, key seats. I have shown diagrammatieally in Fig. 14 apiece of work Sal in which a key seat 85 is being cut by the tool 86mounted within the drill head 10 by holding the handle 36 of the drillstationary, so that the tool 86 will not rotate, and then operating thefeed screw 31 so that it will perform the function of moving the tool 86longitudinally to score the work 81 to form the key seat 85, or scoringthe work l for any other desired purpose.

lllhile I have mentioned some of the many advantages of my improveddrill and some of the uses to which it may be put, I have not attemptedto mention all the uses, but on the contrary it is to be distinctlyunderstood that my invention is not to be confined simply to those usesherein described for it covers any and all uses to which the drill andseparate parts may be put and is to be limited only by the terms of myclaims.
